Patented July 28, 1908.

strike typ'ewri-ting machine-of the general character disclosed in my application No.

' 300039, filed February 8, 1906, although not limited in its application to a key lever machine. Its purpose is to provide a durable, economical and satisfactory manner of mounting the pivotal or anchorage point of a link constituting part of a type bar actuating connection. In my prior application, the

'type bar operating connections have their anchor points in or on a'segment located at the front of the machine. That segment is disposed vertically, its chord being a horizonine and the anchor points or pivotal supports for'tlle front ends of thefront links of the type bar actuating connections are upon posts carried in said segment and having their heads lying in a line corresponding generall to the contour of the upper concave edge of the segment. Furthermore, the segment is disposed at a slight inclination rearwardly so that the pivotal or anchor'points on each side of the center will be located. nearer to the segment in which the type bars are pivoted. The purpose of that arrange ment is to make feasible the use of links of uniform length. I i

The invention comprises an organization wherein the vertically disposed posts "constituting the anchor points of the type bar operatin connections may each be individually roclred about an axis transverse to the machine and securely locked in position. Such adjustment affords a ready means of accurately assembling the machine with the parts in exact position, notwithstanding that some of the parts may not conform precisely to the design with respect to location, or disposition, or exact dimensions.

- In the accompanying drawings, Figure 1 is a front view showing the segment, in which the anchor point posts are. mounted, and

some associated parts: Fig. 2, agplan view thereof: Fig. 3, a-vertic al longitudinal section through Fig. 1:- Figs. 4, 5; and 6 are respectively enlarged detail views showing one of) the vertically disposedanchor posts adjusted in different positions: Fig. 7 com rises a view in elevation and plan of the left and anchor post of the series: Fig; 8, a view in elevation and plan-of the right and anchor post of the series: Fig. 9, a sectional view showing a type bar and its operating connection, ke lever and associated parts properly adjuste Fig. 10 indicates a condltion that may arise in assembling where the parts are so related that the type bar does not lie against its rest or back stop. Fig. 11, a similar view show.- ing .a condition, that may exist in the assembling, in whiclnthe key lever does not lie against its upper stop: and Fig. 12, a diagrammatic vlew illustrating by radial lines the angular disposition of the enlarged heads of the various anchor posts.

The anchor point segment 1 ls formed witha skeleton frame having side posts 2 by which it is bolted to the main frame by bolts 3. As seen in Fig. 3, it is inclined from the bottom slightly toward the rear of the machine and viewed in plan as in Fig. 2 it is .curved transversely, the convex slightly face being at the front. In the front face of the segment. are milled a series of vertical channe s 4, the bottoms or rear faces of which are preferably parallel with the-rear face 5 of the segment. The front open faces of the series of vertical channels 4 are closed by a cover plate 6 secured to the segment by aseries of screws 7 which assthrough the plate and into the body 0, the segment, intermediate channels therein. Below the segment and conforming .in generalcurve thereto is a stepped positioning 'plate' shown, in this instance, as formed of'two parts 8, 8', the flat shoulders on said plate. being respectively below the channels 4. Sacha-positioning plate is disclosed in myg prion-application above mentioned. Its purpose is to support in pro er position the several anchor point posts ocated inthe grooves 4 and resting upon the shoulders of the plate. Each anchor post 9' has its rear face formed with a high point 10 thatbears on the bottdm of the vertical groove 4. Preferably, point is formed by straight bevels extending therefrom upwardly and downwardly. The bottom of the,anchor post is of such width as metal beingrectangular in cross section and their front "edges are straight. For each this 'high tively t e angular position of the anchor post may be varied so as to throw its upper end to the front-or rear. It may be positively locked in any position to which it is adjusted. This will be quite plain on inspection of Figs. 4, 5

and 6. Each post 9 has an. enlarged fiat head 13 for pivotal connection of the front link of the type bar actuating connection. Since the anchor post segment has a longer chord than the type bar segment, the heads 13 of the various'posts should be disposed radially so that lines drawntherefrom through the points on the type bars at which their operating connections are applied will meet at a focus somewhere beyond the type bar segment. This radial arrangement of the flat heads 13' may be accomplished as follows. All of the anchor posts may be blanked out from the same die and their fiat eads 13 be adjusted to the radial arrangement suggested by twisting them. As is plain from the diagram, Fig. 12, the heads of the posts at'the right and left of the series have imparted to them .a greater de ree of angular displacement and this degree essens as the center of the machine is approached.

14 in Fig. 9, indicates a type bar segment of any'suitable construction for a front strike machine. A type bar 15 pivoted therein lies toward the front of the machine upon its rest 16. To the heel of'the type bar is jointed a link 17 hinged at its front end at 18 to the rear end of a link 19 pivotally mounted upon the head 13 of its anchor 0st 14.

20 is the key lever norma y drawn up- Ward by a properly disposed spring .21 against its horizontal stop bar 22 extending across the lower part of segment 1.

23 is. anordinary comb plate for'guiding the key levers vertically and 24 is a vertically disposed link extending fromthe key lever to the frontlink 19 being shown connected thereto (in this instance) at a point in front of the hinge connection 18. If in the setting up of the machine a type bar fails to reach its rest 16, as shown in Fig. 10 in an exaggerated way, the upper end. of the anchor post must be carried to the rear sufficiently to permit the type bar to pro 'erly seat on its rest. This is accomplished liyv screwing up the upper lock screw 11 and easing up the lower lock screw 12 If, as in Fig. 11, the key lever is not brought by its spring up against its up er stop, 22, then by screwing in the lower ock screw and easing up the upper one 11, the head 13 of the anchor post wi be moved forward the action bein to permit the front link 19 to rise and the Trey lever to come against its upper stops. In all positions the lower edge 13 of the anchor post will remain in contact with its seat on the ste ped positioning plate which deter mines t e position, vertically, of the post.
